Today, Porsche decided what everybody thought they would decide: They will build the mid-engined plug-in hybrid 918 Spyder. After all the pomp and circumstance at the auto shows in Geneva and Beijing, it would have been a big let-down if they would have said: “Sorry, it was just an idea. We didn’t really mean it. How about that Cayenne?”

The 918 Spyder car is so nice to the environment, it should only be available in green. It will produce only 70 g/km of CO2, which equates 3 liter of gasoline for 100km, which translates to 78.4 mpg (YMMV). And that in a car that is rumored to have more than 700 horses, will accelerate in 3.2 seconds to 100km and will have a top speed of around 320 km/h, or 200 mph.

The real data will be released in the following months, says Automobilwoche.
